With weighing mechanics located externally, the WF300 series solids flow meters are unaffected by corrosive, abrasive or hot materials. Handling a wide range of product sizes, densities and fluidities including fine powders such as cement, they operate at process temperatures to +450 °F (+230 °C). The flow meters help to improve final products, increase operating efficiency and realize significant cost savings.


Operating with the appropriate SITRANS WFS300 sensing head and a microprocessor-based integrator package, the WF300 series flow meters provide a display of the flow rate, totalized flow and alarms. Outputs are 0/4 to 20 mA proportional to rate, and open collector output for remote totalization.


Dry bulk solids enter the flow guide producing a mechanical deflection as they strike the flowmeter sensing plate before continuing through the process unhindered. The LVDT in the sensing head converts the deflection of the horizontal force into an electrical signal. The integrator processes this signal into a display of flow rate and integrated total weight. The weighing process is immune to the effect of product build-up as only the horizontal force is measured.


WF330 flow meters are totally enclosed with external weighing mechanics, operating with corrosive, abrasive or hot materials. The WF350 operates with aerated gravity conveyors, and includes integral vents and baffles for air separation. For applications with little available headroom, the WF340 flow meters provide a solution.
